Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Herbaceous annual or perennial, simple or branching erect, ascending, or semi-prostrate, to 70 cm tall, strigose, villous, or hirsute. Leaves: Alternate, lance-oblong or oblanceolate, sinuate-dentate or only slightly toothed, to 10 cm long, the lower ones petioled, the upper ones sessile or on short petioles. Flowers: Yellow or white, aging pink or red, petals 5-18 mm long, solitary in the upper leaf axils, hypanthium 15-35 mm long, deciduous after flowering, sepals 4, 6-12 mm long, stamens 8. Fruits: Capsules cylindric, 10-35 mm long, 4-celled, dehiscent. Seeds many, brown, evenly pitted. Ecology: Found in pine forests, damp and disturbed areas, from 1,500-9,000 ft (457-2743 m); flowering May-October. Notes: The deeply incised leaves and small yellow flowers help to identify this species. Ethnobotany: Specific use of the species is unknown, but the genus was used as a compound infusion wash to treat sore skin, and the leaves were boiled or fried and eaten as greens. Etymology: Oenothera is from Greek oinos, wine and thera, to imbibe, while laciniata means torn or deeply cut, referring to the fringed petals. Synonyms: Raimannia laciniata Editor: LCrumbacher, 2011
